LG Water Solutions’ NanoH2O™ TFN RO membranes are playing a key role in Taiwan’s national water reuse initiatives, helping to reliably convert sewage into clean water for two of the country’s six wastewater reclamation facilities.
The Linhai wastewater treatment project (WWTP) and the Fengshan River wastewater reclamation and reuse project (WRRP), built between 2020-2021 and 2018-2019, respectively, can recycle more than 100,000 m3/d of wastewater for Taiwan’s key industrial zones.
Located in the Linhai Industrial Park, the Linhai WWTP treats up to 55,000 m3/d of municipal sewage and converts 33,000 m3/d into high-quality permeate using more than 2,500 pieces of LG BW 400 R G2 membranes. Expansion of up to 60,000 m3/d is possible for the water recycling facility to meet future demands. In the six months since LG Water Solutions supplied its high-rejection anti-fouling RO membranes, the facility has not required a single chemical cleaning to treat secondary effluent, while low feed pressure has been maintained for added energy savings. Similarly, the Fengshan River WRRP is also relied on to supply clean water to the Linhai Industrial Park. A 25,000 m3/d facility first came online in 2018, followed by a 45,000 m3/d in 2019.
The project found that its existing RO membranes experienced issues such as high differential pressure, leading to frequent cleanings and RO system shutdowns, as well as poor performance recovery after cleanings. As a result, the facility reached out to LG Water Solutions to find a more robust membrane replacement. LG Water Solutions supplied its BW 400 R Dura, a high durability membrane, to replace one train at Fengshan River WRRP at the end of 2020. In both projects, the membranes’ durability and reliable performance have increased OPEX savings due to reduced energy and chemical consumption and labor, as well as increased plant uptime. Peter Wang, Commercial Director of Greater China at LG Water Solutions, said: “Like many water-scarce regions, Taiwan relies on recycled wastewater to provide clean water, alleviate shortages, and stabilize its industrial economy. Our partnership with the Linhai and Fengshan River wastewater reclamation facilities doesn’t just help to reduce their costs and cut downtime, it provides a great example of how an advanced wastewater treatment process can lead the way in sustainable water recycling.”

Background
Hit by severe drought, water supply disrupting typhoons, and rapid industrialization, especially in microchip fabrication, the Taiwanese government enacted the Reclaimed Water Resources Development Act (RWRDA).
The act invested over NT $15.2 billion (US $465 million), resulting in six wastewater reclamation facilities constructed between 2016 and 2021, supplying nearly 280,000 m3/d of clean water to Taiwan’s key industrial zones.
The Fengshan WRRP is the first among the six planned municipal wastewater reuse facilities. The Linhai WWTP was completed in 2021 and is the second wastewater facility completed, also supplying clean water to the Linhai Industrial Park of the Kaohsiung region.
The Kaohsiung City Government awarded the project to Blue Whale Corporate, a joint venture formed by CTCI Corporation and Hsin-Dar Environment (HDEC), two of Taiwan’s largest EPC contractors.
LG Water Solutions continues to provide resiliency to Taiwan’s drought challenges. Between 2020 and 2021, LG supplied its seawater and brackish water RO membranes for emergency mobile UF/RO water purification units, installed at three water resource recycling centers.
In phase I of the project in December 2020, the membranes enabled 13,000 m3/d seawater desalination and 9,000 m3/d municipal wastewater reuse. Within four months, phase II enabled a further 13,000 m3/d of seawater desalination.
